Human Heart Anatomy Diagram - Educational Medical Illustration #275717 (License: Personal Use)

This stylized medical illustration depicts the internal anatomy of the human heart, including the right and left atria and ventricles, semilunar and atrioventricular valves, aorta, pulmonary artery, and vena cavae. Each structure is color-coded for clarity-red for oxygenated blood pathways, blue for deoxygenated, and purple for mixed or transitional zones-making it ideal for teaching cardiovascular physiology. The artist’s signature “MARTIN” appears in the lower-left corner.

Used in educational websites, medical textbooks, e-learning modules, and patient brochures to explain cardiac structure and function; matches user intent for visual learning, anatomy study, or health literacy improvement.
